Func viscluster

A VVIS-optimising internal brush entity available in the Orange Box engine. It allows you to manually tell VVIS that the leaves inside its volume can all see each other, which is useful in large open areas where the computer's calculations would otherwise take a very, very long time to complete.

It should be textured with tools/toolstrigger.

Warning:The brush should not cross the surface of a water brush. If it needs to, create a separate second entity on the other side.

Note:This entity reduces compiling time by letting VVIS avoid calculations. It does not change the location or the number of leaves. Use Func_detail, Hint brushes and areaportals to optimise runtime performance!
